OF THE earth's SURFACE. 207 



I 



The observations I have made on this dikivian subject, has 

 been confined to a small range of covmtry, comprehended be- 

 tween our two seas, because it is only of that small range that 

 I can speak with any tolerable certainty ; but I have reason to 

 believe, that other members of this Society, possessed of every 

 requisite advantage, are ready to take up this curious subject, 

 and to pursue it with vigour. On that account, I have the less 

 scruple in bringing forward views, that may to many appear 

 extravagant, since there is reason to expect, that whatever er- 

 rors I may have committed will soon be rectified. 



I trust also, that the facts brought forward in this paper, are 

 susceptible of an extensive application, and that they furnish 

 the means of ascertaining the direction of diluvian inundations 

 across the great continents. By a comparison of directions, 

 these tremendous agents may be traced to their source. The 

 native place of the granite blocks, mentioned in the 1st part of 

 this paper as occurring on the shores of the Baltic, and also of 

 those on Mount Jura, may thus be discovered. If both sets came 

 from Mont Blanc, we may expect to find between it and the 

 Baltic Sea a system of crag and tail like that in the neighbour- 

 hood of Edinburgh. If the Prussian blocks came from another 

 quarter, the circumstance will soon speak for itself, and the 

 question will probably be decided by the first traveller ac- 

 quainted with these ideas, who passes,- ever so rapidly, through 

 those countries. 



In the same manner, we may expect to see light thrown on 

 the history and circumstances of that tremendous event alrea-
